The Santori family built a rectangular swimming pool in their backyard. The length of the pool is the 4 times the width. A cemen

Usimov [2.4K]

Answer:

The area of the pool and deck is equal to

$A=(4w+12)(w+12)$ or $A=4w^{2} +60w+144$

Step-by-step explanation:

Let

L------> the length of the rectangular swimming pool

w------> the width of the rectangular swimming pool

we know that

$L=4w$ ------> equation A

The area of the pool and deck is equal to

$A=(L+6+6)(w+6+6)$

$A=(L+12)(w+12)$ ------> equation B

substitute equation A in equation B

$A=(4w+12)(w+12)$

$A=(4w+12)(w+12)\\ \\A=4w^{2} +48w+12w+144\\ \\A=4w^{2}+60w+144$

In each of the following ,make y the subject and hence find the value of y when a=2, b=3 ,and c=4.

zvonat [6]

Part i

$\dfrac{2a-7}{6y} = \dfrac{3b-5}{2c}$

$y = \dfrac{ 2c(2a-7)}{6(3b-5)} = \dfrac{c(2a-7)}{9b-15}$

Substituting,

$y = \dfrac{4(2(2)-7)}{9(3)-15} = \dfrac{ -12}{12} = -1$

Answer: -1

Part ii

I'm not sure that one's typed in correctly but I'll solve it as written.

$3-34y + 2a = \dfrac{3b-5}{2c + 1}$

$34y = 3+2a-\dfrac{3b-5}{2c + 1}$

$y = \frac 1 {34}\left(3+2a-\dfrac{3b-5}{2c + 1} \right)$

We're not asked to simplify it so I wont. Substituting,

$y = \frac 1 {34}\left(3+2(2)-\dfrac{3(3)-5}{2(4) + 1} \right) = \frac 1 {34}(7-4/9) = \dfrac{59}{306}$
